How to get Google Play credit for free

Google has released a new app for Android devices that rewards users with Google Play store credit when they answer surveys.

The app is called Google Opinion Rewards and is available for free. Users can download the app from the Google Play store and quickly get to answering surveys -- I set up the app pretty quickly.

To get Google Play credit, users must first link the app with their Google Wallet account, where they will receive the credit. Then, users must answer a few questions about themselves. Google says those questions are necessary so the app can send users surveys that are relevant to them. One of the questions asks if the app can send users surveys that do not reward credit -- I made sure to say that was not OK.

Once all is set up, users can start their first survey. Google says each survey is no longer than 10 questions, and every time a new survey is ready, the app will send users a notification on their Android device. Surveys will be available once per week, the app's description reads.

It's unclear how much credit each survey is worth, but a video for the app -- which can be seen above -- shows a user receiving $1 for doing a survey. That's about enough money for one app.
